Figure 10 shows, partly in section, an im! plement for positioning thefastener illustrated by Figure 11 which is the same as the one shown byFigure 7 but on an enlarged scale.

Figure 10a is 'a 1010d of'Figure 10.

Figures 12, 13 and 14 relate-to a modification applicable preferablywhere the overlapping of broadly corrugated plates is desired to bereduced as much as possible. The device shown by Figure 12 is suitablefor timberwork,.the one shown by Figure 13 for metal framing, and theone shown by Figure lfi'comprises an articulation or link analogous tothe one shown by Figures 7 cross-section on line 8 and 9 while theattachment thereof can be effected by meansA of the implement repre-lsented in Figure 10.

In all the tiguresthe same reference letters denote the same parts.

The' securing or fastening device shown by Figures l, 2, and 3, isessentially constituted.

by a, metal hook A, preferably made of iron, the top portion B ofvvl'iiclilisgthreaded, While its bottom portion C is bent or curved soas to offer a shape fitting the section of the framework beams orgirders D (Figures 2 and 3).

On the stem of the hook 'A is sli-dably mounted a sleeve F provided atits lower end with a sheet-,metal member E shaped to fit thecorrugations of the plates K that make up the roofing. .Above sleeve Fis positioned a square disk G made of malleable metal, preferably oflead, upon which is superimposed a cap topped in its turn by a washer I,preferably made of lead. A nut J screws on threads B. Optionally an ironwasher may be interposed between said nut and washer I.

I usethe above described device in the following inanner:

Having laid in alinement on the framing the corrugated or smooth platesK (Figures 2 and 3)' I mark the fastening points thereon by means of achalk line, after which I pierce lsaid plates at the proper placesthrough the tops of the corrugations, as usual, takingcare tlat theholes be of a diameter slightlyy larger than the diameter of 'hook Ainorc er to allow the roofing suficient Aplay for expansion andcontraction.

I lift up the plates at vthe points wherethey overlap` and-separate thestem of each hook'A from all the above described mov' able parts. )Ithen introduce between the plates the sleeved separating or .partitionmember E-F so that the sleeve thereof will pass through the hole in theupper plate and protrude above the roofing (Figures 2 and 3).v 1I. thenintroduce'tlie stem of the fastening member 'into sleeve- F, whilehooking, by .means of portion C, themetal beam or girder'D.. I` then puton the leaden disk G. so' that yits diagonal willbe set exiactly inthedirection ofthe roofs slope; I next position the-closing cap I-I, thebases of which, preferably4 squarel andl slightly ably be rounded orrecessed so as vto prevent' the hammering from damaging thethreads. Ithen lay the next plate by engaging/the` ^it also'will be` in thedirection of the roofs slope. I then cover cap H with leaden washer I,and, if I so desire, with a sheetmetal or an iron washer, and I clampand lock the whole together by tightening nut J.

Of course, the fastening'device for metal framework may' be made of thetype illustrated by Figure 4. In this case, the hooked rod or bolt isanalogous to the aforedescribcd one and the sheet-iron plates of theroofing are joined by means of two nuts J 1-J z com'- bined with twomalleable metal washers` I1 I".

,The lower nut J 2 and its washer I2 are for the purpose of preventingthe pressure exerted by the upper nut J from exert-ing harmful action onthe conrugations of plates K.

For securing said plates, I first tighten the upper nut J so that saidplates will rest truly on4 the frame work, and, then, I tighten jam-nutor check-nut J. e I will now describe, by reference to Fig'- ures 5 and6, a fastener adapted to secure roofing on timber-work and battens.

In this case, the fastener is formed of a metal rod A1, threaded at itstop portion B1, and' comprising, fixed at X by any suitable means, aconvex metal separating or spacing member El analogous tothe one shownat E in Figures 1, 2 and 3.'

The lower end of rod A1 is tapered or pointed and provided with barbs orflukes L. f A leaden washer I (and, if desired, an

iron washer) is superimposed over the sheet? iron member E1 and a-nutJ2' is screwedon the 'threadedportion B1.l Y'

This device is used as follows:

Having properly laid thesheetiron plates and completed theirperforation, as hereinbefore explained, I' form holes in the rafters orsuch like so as to facilitate the vdriving in of rods A1. I then pushback the first row of plates one plates width, and I secure the rstplate by means of rod A1,`prceed ing in such a way that member E1L willrest truly on the corrugationjofsaid plate. Head M of the fastening rodVshould'preferlatters holes on the threaded portions of .v vthecfastenings. I position the leaden washer I, and if any, theaforementioned iron washer, and I clamp the whole together by means ofnut'J. l

Of course, the devices just described can be 'applied in the same way asabove foi' securing smooth plates, but, in the latter case. thel membersE-E1 should be flat in- `stead of convex.

The above described devices offer numerous advantages, to wlt:

In the -case of corrugated iron sheets or' plates the latterscorrugations are reinforced at-the fastening points by the convexseparating .member positioned between the plates so that the pressure ofthe nut can no longer have thel least detrimental iniuence. 1vVater,meeting' 4first of all the part of the cap which is lined with lead orother malleable metal, gets, therefore, but very little hold, and isdivided by the cap and is immediately led into the troughs of thecorrugations. If, however, water eventually manages to find its wayunder the base ofthe closing cap land of. theleaden disk, it would meetthe convex separating member E and its sleeve F, which projectsthrough'the roofing plates-'into the closing cap. Such water would thenjagainbe led into vthe troughs of the corrugations and would drip on the`corrugated plate'next Since the convex separating members reinforce theplates, my. invention offers a better foothold 'on corrugated rooiigs,es-

peciallyif care is taken to walk as nearly as poss1ble along the linesof fastening points. Furthermore, the lf'aste1 1i11g:, devices protrudea good deal, thereby permitting rooflayers to use them as supports forany scafoldmgs, ladders, etc., .whereby the handling of roofingplates isgreatly facilitated. In the .case of roofing to- 'be secured ontimber-work or battens l the same advantages obtain as towatertightness,'with this difference,'howe ver, that any .wateifindingits way under the top washer irojllld'- meetr the member E1 which isfast on threaded rod A1. Q' l The fasteningrods are provided with barbswhich hold them rmlly .'in'thetim'ber orA wood and they cannot fshakefthemselves loose since they have to carry the-."weightof the roofing andare thereby kept secure. Indeed, even if they actually become loose, apractical impossibility, .no infiltration o'f water could occur'since"there: would a1- ways. remain: the separating member bolted los vItshould benoted-thfa cases, the 'i separating members, can be made moreorvv less long. The Alonger'they are the more the roofingwillv-'bereinforced and the 'better supported; so that it will become1.20` orplates apply alsogto smooth metal sheets Another characteristicof said device relates to the peculiarrand special construction of themember that serves to lock the coniponenty parts of the device on theoverlapping surfaces.

' The device shown by Figure 7 comprises a nietal rod A4, having topportion B threaded and its lower portion linked to a tapered rod A5provided, for instance, at its free `end with barbs L.

be effected by means of,

The linking can n A3 or'by any other suitsay, two eyelets A2, ablemeans. made disconnectible.

- Said articulated rod is combined with: a separating'member orpartition E fitted at its upper portion with; a square disk G ofmalleable metal; a suitably shaped iron cap H; a cover Z, made of castiron or of any other metal and formed internally with a dependinghemispherical portion Y provided with a threaded hole X1. Said piece Zis locked'by means of a check nut or jam nut W screwed on the end of rodA4k which terminates in a point. A wedge Z1 (Fig. 7a) ma be provided andmay be driven through a s ot B1 in the threaded-,part B ofsaid rod toprevent any loosening of the check nut.

'Ihe device illustrated by Figure Sis intended for securing roofings onmetal beams fastening device of Figure or girders. It only differs fromthatshown by Figure 7 by the` feature that rod A4 is provided with ahookA6 which is shaped to fit the section of the metal beam.

The device illustrated by Figure 9 is designed for the purpose onbattens or plane surfaces and comprises at its lower parta small plate Pwherein is an eye A".

Figure or implement the articulated 7, represented on an enlarged scaleat Figure 11.

Said tool is composed of a metal tube T permitting rod A4 to be passed'through.

protect the threading 4B of rod Af. In its lower portion, tube. T hassuitably formed and sized recesses t0 permit the sliding of eyes A2 andA3.

The overlapping plates K are y laid on one another, as sho)wn by Figure7 and are formed with holes at suitable places. Through these holes Irun the tool ory implement above described, said tool holding thefastening member. I rest the lower end of tube T on the frame work and Istrike blows until it is entirely As already stated,l it can beofsecuring roofing f rious elementsconstituting the fastening device inthe same manner as afore explained.

'Ilie modification shown by .Figure 12 is adapted for timber-work. Itpermits, as h ereinbefore stated, to spare as much as possible theoverlapping of broad-corrugated plates. This device is constituted by arod A8, threaded at its top portion B, which is tapered andy terminatesat its bottom in barbs L. In the case of metal girdersasaid barbs may bereplaced by la hook A9 shaped to fit the girder section.

Said rod mayv` also have an articulation of any kind, as in the case of4Figures 7, 8, 10 and 11. In all cases it'is combined with a socket orsleeve F2 providedl with an oval base-E2 shaped to conform to thesection of the corrugation. The outside of said sleeve is threaded. Awasher G2, made of lead or other malleable metal, an iron washer H2 andan outer socket or.,sleeve I2 complete the device. The lower part ofsocket I2 has itsinside threaded so as to screw on sleeve F2, and itsupper part, also threaded on the inside,is adapted to be screwed on rodA8.

Said socket I2 a suitable spaniier. with four or six faces so as to beoperated like an ordinary square oi` hexagonal nut.

For laying the roofing-.plates I proceed as follows: j

I perforate said plates at the required places. I then introducel sleeveF2 into a hole so made. I screw o n .the sleeve the leadeii washer G2 sothat the sleeve will be properly held in the plate. I

It should be knoted that when laying roof-y ing plates on a'metalframing the fastening rods should be introduced from below.

If articulated rods are used for laying roofing on timber-work, theyshould, ofA course, be first secured on the rafters by means of thecontrivance shown by Figure 10.

The above .described device will .do away with all danger of injury tothe plate corcan be put on by means of Its outside may be made rugationseither from the pressure ofthe clamping 'nut or from careless orexcessive driving in of nails or fastening screws. vBy being screwed onthe thread of rod Aa the Vfixing socket I2 engages the threads on sleeveF2'and, by'bearing on iron washer H2, draws support for the plate,

face of said washer.

prevent any infiltration of water that might oc'cur in case rod Asshould become loosened from the under-roofing, since the joint of thefastening point of the plate must al-v ways remain gripped betweensocket I2 and sleeve F2' which Aare screwed into one another. Y

Obviously, the latter device can be used not only for broad corrugatedbut also for ordinary corrugated iron roofing.

Having now particularly ascertained and described the nature of my saidinvention as well as the manner in which the same is to be performed Ideclare that what I claim is:
